Benign prostatic hyperplasia (BPH) is a very common disease of old male persons. Some recent epidemiological studies have revealed that to large extent lifestyle factors associated with metabolism including obesity, blood glucose, exercise, and diet also contribute substantially to the development of these conditions.
BPH is defined as an enlarged prostate gland that can cause uncomfortable urinary symptoms, such as blocking the flow of urine out of the bladder.
The prevalence of BPH is age-dependent, with initial development usually after 40 years of age and more than 50% of men in their 60s and up to 90% of men in their 70s -80s years have some symptoms of BPH. The prostate gland increases in size as the age advances, making BPH one of the most common age-related conditions in men.
